By filtering shorter wavelengths, the image becomes more contrasty and structures that are normally lost become more apparent. This filter is particularly effective for observing Mars: polar caps, dust storms and dark structures on the surface stand out.<br>For Jupiter and Saturn, this filter can also help to enhance shadows and atmospheric details. In addition, it attenuates the brightest moonlight, making fine details in craters more visible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The mount is of sturdy anodized aluminum with a thin profile of only 5 mm, making it easy to use the filter in a zenith mirror or filter wheel. The filter glass is completely homogeneous and double-threaded, making it easy to combine with other filters. Supplied in a sturdy protective box for safe transport and storage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Filter type:<\/strong> Red color filter #25<\/li>\n\n\n\n<li><strong>Format:<\/strong> 2 inch thread<\/li>\n\n\n\n<li><strong>Material mount:<\/strong> Anodized aluminum<\/li>\n\n\n\n<li><strong>Thickness Rating:<\/strong> 5 mm<\/li>\n\n\n\n<li><strong>Usage:<\/strong> Visual observation<\/li>\n\n\n\n<li><strong>Series:<\/strong> Basic<\/li>\n\n\n\n<li><strong>Compatible with:<\/strong> 2\u2033 eyepieces, zenith mirrors and filter wheels<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Application<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With this filter you see:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mars: striking polar caps, dust storms and surface differences<\/li>\n\n\n\n<li>Jupiter and Saturn: better visibility of atmospheric details and shadows<\/li>\n\n\n\n<li>Moon: sharper image and more contrast in bright moonlight<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<article class=\"w-full text-token-text-primary focus-visible:outline-2 focus-visible:outline-offset-[-4px]\" dir=\"auto\" data-testid=\"conversation-turn-35\" data-scroll-anchor=\"true\">\n<div class=\"text-base my-auto mx-auto py-[18px] px-6\">\n<div class=\"mx-auto flex flex-1 text-base gap-4 md:gap-5 lg:gap-6 md:max-w-3xl lg:max-w-[40rem] xl:max-w-[48rem]\">\n<div class=\"group\/conversation-turn relative flex w-full min-w-0 flex-col agent-turn @xs\/thread:px-0 @sm\/thread:px-1.5 @md\/thread:px-4\">\n<div class=\"flex-col gap-1 md:gap-3\">\n<div class=\"flex max-w-full flex-col flex-grow\">\n<div class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 whitespace-normal break-words text-start [.text-message+&amp;]:mt-5\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"28a009d2-3136-4224-8ee5-30c9a1a2ece5\" data-message-model-slug=\"gpt-4o\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[3px]\">\n<div class=\"markdown prose w-full break-words dark:prose-invert dark\">\n<p data-start=\"199\" data-end=\"323\">Rood kleurfilter 2 inch \u2013 Omegon #25 maakt kleine details op Mars en andere planeten beter zichtbaar dankzij sterk contrast.<\/p>\n<h3 data-start=\"325\" data-end=\"354\">\u00a0<\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n","protected":false},"featured_media":24887,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[126],"product_cat":[56,588,3140],"product_tag":[],"class_list":["post-24882","product","type-product","status-publish","has-post-thumbnail","product_brand-omegon","product_cat-telescoop-accessoires","product_cat-filters","product_cat-maan-en-planetenfilters-kleurfilters","product_shipping_class-licht","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"bundled_by":[],"bundle_stock_status":"instock","bundle_stock_quantity":null,"bundle_virtual":false,"bundle_layout":"","bundle_add_to_cart_form_location":"","bundle_editable_in_cart":false,"bundle_sold_individually_context":"","bundle_item_grouping":"","bundle_min_size":"","bundle_max_size":"","bundle_price":[],"bundled_items":[],"bundle_sell_ids":[],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":24876,"url":"https:\/\/staging.telescoop.nl\/en\/lichtrood-kleurfilter-2-inch-omegon-23a\/","url_meta":{"origin":24882,"position":0},"title":"Light red color filter 2 inch -
